Luis Diaz's father will reportedly be released 'within hours' as talks continue between the Colombian Government and his captors, the National Liberation Army (ELN).
The Colombian Government revealed on Thursday that the ELN had been responsible for the kidnapping of both Diaz's parents last weekend.
Colombian newspaper El Tiempo reported authorities have been promised by the ELN that Diaz's father will be released within the next few hours.
Members of the ELN group have reportedly claimed to the Colombian magazine Semana that they were unaware members of the organisation had kidnapped Diaz's parents.
